That may be true in this case, but it's hard to say. It's been the policy of a few Agency publishers to drop the price of the ebook (usually from $14.99 to $12.99) once that book is on the NY Times Bestseller list. Not sure if Hachette is one of those publishers or not.

Interesting, I did not know this, and it actually sounds counter-intuitive. Wouldn't it make more sense to have a low intro price and raise it after the book makes the list? That's how many self-publishing authors operate: give the book away for free, generate great revies, then raise the price. Hmmm. I will never get publishers.
